CAR-BUFFING MECHANISM.

SPECIFICATION formingpart of Letters Patent No. 517,378, dated March 27, 1894.

Application filed April 24, 1893. Serial No. 471,598. (No model.)

To aZZ whom it may concern:

Be it known that I, HARRY O. BUHOUP, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented or discovered certain new and useful Improvements in Car-Buffing Mechanism, of which improvements the following is a specification.

The invention described herein relates to certain improvements in car coupling and buffing mechanism, and has for its object a connection from the coupling mechanism at one end of a car to the buffing mechanism at the opposite end of the car, so arranged that an inward or outward movement of the coupling mechanism will effect an outward movement of the buffing mechanism, for the purpose of reducing the independent to and fro movements of the cars in a train.

In general terms, the invention consists in the construction and combination substantially as hereinafter more fully described and claimed.

In the accompanying drawings forming a part of this specification, Figure l is an inverted plan view of the draft and buffing mechanism of a car, embodying my improvement. Figs. 2, 3 and 4 are sectional detail views illustrating certain modifications.

In the practice of my invention, the coupling mechanisms are of the Janney or any other suitable type or construction, consisting of the couplers 1, 1 the draft springs 2, 2 and follower plates 3, 3, the springs and follower plates being arranged with straps or spring-pockets 4, 4, connected to the barrel of the coupler by bolts 5, 5 The buffing mechanisms consist of the stems 6, 6 projecting through the end sills of the car, face plates 7, 7 equalizing levers 8, 8*, loosely connected to the rear ends of the stems and springs 9, 9, surrounding the stems and interposed between the equalizing levers and shoulders on the stems.

The upper ends of levers 10, 10, which are pivotally mounted on pins ll, 11, supported by the center sills of the car, are connected to the equalizing levers 8, 8, at points about midway of their length. These levers extend down around the coupler barrels as shown in Fig. 1, or through slots in the same as shown in Figs. 2, 3 and 4, and have their lower ends connected to the tail pins or bolts 5, 5, by eye bolts 19,19 and to levers 12,12 ,atpo1nts intermediate of their ends. These levers 12, 12 have one end pivoted to one of the center sills of the car, While the other ends are connected by rods 13, 13% to one end of the floating levers 14 and 14, which are arranged transversely of they car, and pass through slots or between lugs 15 on the bolts 16, 16, connect-ed at their front ends to the couplers, so as to move back and forth therewith. Fulcrum pins 17, 18, and 17 18, are secured on the center sillsor other portion of the car, on opposite sides of the floating levers. It will be observed that the floating lever 14, formlng one of the connections of the buffing mechanism at one end of the car is connected to and operated by the bolt 16 of the coupler 1, at the opposite end of the car. As the couplers are pulled out, the levers 14 and 14 are shifted through the medium of the bolts 16, 16 During this movement of the couplers and floating lovers, the pins 17 and 17 serve as fulcra, and, hence, the floating levers exert a pull on the rods 13 and 13 and so shift the levers 12, 12 and yokelevers 10, 10, as to push the equalizing levers 8, 8, and the buffing stems and plates outwardly. As the couplersare forced inward, the floating levers are similarly shifted, the pins 18, 18 serve as fulcra, but this movement of the floating levers also imparts a pull on the rods 13, 13, thereby shifting the buffing stems and plates outwardly.

It will be observed that whether the couplers are moved out orin, the movement of the buffing mechanism is always out, the floating levers, when the couplers are pulled out, operating as lovers of the third class, while they operate as levers of the first class, when the couplers are moved in. The connection between the yoke lever and the tail plus or bolts is such that when the coupler at one end is forced in, the yoke lever will be so shifted as to cause an outward movement of the buffer plate at the same end. As hereinbefore stated, both buffer plates can be caused to move outwardly by the inward movement'of one of the coupling mechanisms, the move ment of the buffing mechanism at the same end as the coupler being transmitted from the coupler to the opposite end of the car and then returned to the bufling mechanism by the system of levers hereinbefore described.

As shown in Fig. 3 only one central bnffing stem and plate may be employed, in which case the equalizing lever is omitted.

I claim herein as my invention 1. The combination of a bufting mechanism arranged at one end of acar, a coupling mechanism arranged at the opposite end of the car, and connections interposed between said mechanisms, whereby a longitudinal movement of the coupling mechanism either in or out will shift the buffing mechanism outwardly, substantially as set forth.

2. The combination of a bufling mechanism arranged at one end of a car, a coupling mechanism arranged at the opposite end of the ca r, and a system of levers connecting said mechanisms, whereby the coupling mechanism when shifted longitudinally either in or out will shift the buffing mechanism outwardly, substantially as set forth.

3. The combination of a buliing mechanism arranged at one end of a car, a coupling mechanism arranged at the opposite end of the car, a floating lever having two fulcra, and connected to the buffing and coupling mechanisms, whereby said lever is adapted to effect an outward movement of the buffing mechanism, when shifted either in or out by the coupling mechanism, substantially as set forth.

4:. The combination of a coupling mechanism arranged at one end of a car, a lever movable in and out with the coupling mechanism and having two fulcra, a connection from said lever to a lever at the opposite end of the car, and a buffing mechanism operated by the latter lever, whereby a movement in or out of the coupling mechanism will force the bnEer outwardly, substantially as set forth.

5. The combination of a coupling mechanism at one end of the car, a bul'fing mechanism at each end of the car, connections between the bnfling mechanisms and the coupling mechanism, whereby a movement in or out of the coupling mechanism will force both buffing mechanisms outwardly, substantially as set forth.

In testimony whereof I have hereunto set my hand.
